85523-03-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 85523-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,2 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85523-03:
(7*8)+(6*5)+(5*5)+(4*2)+(3*3)+(2*0)+(1*3)=131
131 % 10 = 1
So 85523-03-1 is a valid CAS Registry Number.

HETERODIENE SYNTHESES-XXV KINETICS OF THE REACTION OF ETHOXYETHENES WITH 1-PHENYL-4-BENZYLIDEN-5-PYRAZOLONE. ACTIVATION ENERGIES VS ENERGY GAINED IN THE CYCLOADDITION.

Coda, A. Corsico,Desimoni, G.,Righetti, P.P.,Tacconi, G.,Buttafava, A.,Faucitano, F. Martinotti

, p. 331 - 336 (2007/10/02)

The kinetics of the reaction between 1-phenyl-4-benzyliden-5-pyrazolone and ethoxyethenes have been studied by quantitative spectroscopic analysis in xylene at various temperatures.These 1,4-cycloadditions are HOMO-ethoxyethene controlled but Sustmann's approximation of the general perturbation equation cannot be used to rationalize the results since meaningless relationships are obtained by plotting the log of the rate constants vs the inverse of ethoxyethene HOMO energies.If the energy gained in the cycloaddition, calculated by MO energies and coefficients, is plotted vs the log of the rate constant a good relationship is obtained which results better if the entropy factor is excluded.
